WATCH-MAKERS TWEEZERS.

SPECIFICATION forming part of Letters Patent N0. 420,125, dated January28, 1890.

Application iiled August 21, 1889. Serial No.321,507. (No model.)

To @ZZ whom it may concern:

Be it known that I, EDGAR P. SwArN, a citizen of the United States,residing at Yazoo City, in the county of Yazoo and State of Mississippi,have invented certain new and use ful Improvements in Vatch-MakersTweezers; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.V Y

This invention relates to certain new and useful improvements inwatch-makers tools 5 and it has for its object to improve upon thatclass of tools which are commonly known as watch-makers tweezers.

The immediate object of the invention is to provide a tool of thisdescription which may be readily adjusted, so as to adapt it for use invarious classes of work, it being possible to easily and quickly convertthe tool into either a heavy and rigid set of tweezers suitable for usein work in which a tool of this description is required; or it may withequal facility be converted into a sensitive tool suitable for the moredelicate classes of work, or into a set of tweezers having doublegraspingpoints upon each of its arms, thus adapting it for use where aiirm and secure hold upon the article held is necessary.

To the above ends, and to such others as the invention may pertain, thesame consists in the'peculiar combinations and in thenovel construction,arrangement, and adaptation of parts, all as more fully hereinafterdescribed, shown in the accompanying drawings, and then specically denedin the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, like letters of reference indicating like partsthroughout the several views, and in which drawings Figure 1 is aperspective view of a tool constructed in accordance with my invention,in which view the adjustable arms are shown as withdrawn or shortened.Fig. 2 is a similar view, in which the arms are shown as lengthened orextended. Fig. 3 is a plan view, partly in section.

Reference now being had to the details of the drawings by letter, Adesignates the pliers proper, which are made in the usual form andpreferably of a single piece of heavy spring metal. zersAisprovidedwithalongitudinal groove B.

C C are supplemental arms or plates corresponding in size and shape withthe arms of the tweezers proper, and are fitted upon the inside face ofeach arm, as shown, being secured against lateral displacement by thelugs or rivets D, passed through the longitudinal slots in the outerarms of the tweezers A and secured to the arms C.

E are lugs, which are secured to the inner or supplemental arms C, andthese lugs fit loosely within the slots B, and serve as 11andles for usein moving the supplemental arms longitudinally, as will be readilyunderstood.

It will be readily seen from the foregoing description that the innerarms C may be readily adjusted at any point when desired, and that whenthey are extended to their extreme outer point of adjustment, as shownin Fig. 2 of the drawings, the tweezers will be extremely sensitive andin condition for use in delicate work. It will also be seen that whenthe supplemental arms are withdrawn so as to coincide with the outerarms an exceedingly strong and serviceable tool will be produced. Byslightly extending the inner arms a set of tweezers having doublegrasping-points upon either arm will be produced.

Having thus described my invention, what l claim to be new, and desireto secure by Letters Patent, is l l. A pair of tweezers havingsupplemental adjustable arms, substantially as described.

2. The combination, with the arm of a pair of tweezers, of asupplemental arm adjacent to said arm and longitudinally adjustablethereon, substantially as described, and for the purpose specified.

3. As an improved article of manufacture,
